A Workshop Summary of 'Model Predictions of the Piston-Driven-Compaction Experiment
Abstract
A JANNAF Propulsion Systems Hazards Subcommittee Workshop was held on 25-26 october 1988 in conjunction with the 25th JANNAF Combustion Meeting in Huntsville, AL. The area of interest is the transition to detonation in confined granular energetic material. This workshop focused on the acceleration of a strong compaction wave, before the onset of detonation. The objective was to compare model predictions to four Piston-Driven-Compaction experiments involving two different ball propellants. These were true predictions, since the experimental data were not released until the second day of the workshop. Several of the models came close to the compaction wave locus. However, it was more difficult to predict wall stress time-history seen by two transducers at fixed locations along the tube. The timing of a runaway is extremely sensitive to the intense competition among sources of reaction and heat loss.
